This program examines block groups that only partially intersect with community districts.

In the cd.RData file, Rosedale has cd_id=209, Swope Park has cd_id=110.

Interesting neighborhoods might be Terrace Lake Gardens, Colonial Square, Hidden Valley, Crossgates because each of these coincides with a single tract.

Ruskin Heights Eastwood Hills East have four tracts totally inside. Bannister Acres has two tracts totally inside.

Swope Parkway-Elmwood has three tracts, one totally inside and two partially inside. Vineyard is also similar. Glenhaven, East Swope Highlands has two tracts, one totally inside and one mostly outside.
